Hikikomori is a Japanese term that means long term social withdrawal typically by adolescent and adult males. Usually the concept of Hikikomori excludes symptoms of schizophrenia. Today hundreds and thousands of Japanese people are considered to withdraw from society.

All articles above are interviews with members of Association of Selective Mutism in Japan who experienced selective mutism. ASMJ is one of the major selective mutism support group in Japan, which, in my view, emphasizes adult selective mutism.

We can find many Japanese Hikikomori people who really suffer(ed) or seem(ed) to suffer from selective mutism in academic literature, books, on Internet websites, etc. But it is not clear how many people suffer from such difficulties.

According to a study by Ministry of Health, Labor and Welfare, out of 149 Hikikomori cases which visited 5 Mental Health and Welfare Centers and received diagnoses of mental ilnesses, one case was diagnosed as selective mutism. But it is not clear whether about 0.67(1/149) percent of Hikikomori people have selective mutism because most Hikikomori people do not visit Mental Health and Welfare Center.

Little is known for certain about Hikikomori people with selective mutism. Most writings are their personal experiences or case study. Diamond Online's article is no exception.
